The Ethereum community has proposed upgrading the eth/73 protocol to support the propagation of raw signed witness data.

BlockBeats news, November 12: Ethereum developer Marchhill submitted draft EIP-8437, proposing to propagate Proof Wrapper data via the eth/73 protocol and add an optional mode that allows transactions to submit raw signatures to an aggregator without pre-generating a STARK proof. The proposal supports directly propagating authenticated program packages with transactions and executing independent checks of specified programs in a resource-constrained sandbox to verify witness data.

New programs do not require separately developed native adapters for each signature scheme. In addition, the proposal plans to limit batch queue size, clean up expired transactions, and recheck records before formally generating proofs to support retries after failure. The proposal is currently still in the Draft stage and has not yet been merged. Developers noted that VM and key-binding consistency verification, cryptographic verification, and performance testing are still incomplete, and benchmarking has not yet been conducted.
